The Calvert County Sheriff’s Office is investigating a Monday afternoon collision between a medic unit and a passenger car that resulted in one man’s death.

At 4:26 p.m. Monday, the sheriff’s office patrol bureau and crash reconstruction team responded to Route 2/4 and Sixes Road in Prince Frederick for a reported serious car accident involving Calvert Advanced Life Support vehicle Medic 103 and a passenger car, according to a sheriff’s office press release.

Through investigation, deputies determined a 2009 Chevrolet Suburban, the CALS Medic 103, driven by paramedic Katie A. L. Kreider, 23, of Prince Frederick, was traveling south on Route 2/4. Deputies said Kreider was responding to a 911 call for a heart patient in the Lusby area and the vehicle was being operated in an emergency capacity with emergency lights and siren activated.

A black 2009 Toyota Camry, driven by Allen Leroy Parker, 75, of Prince Frederick, tried to drive from Sixes Road across the southbound lanes of Route 2/4 to make a left turn and travel north as the Suburban was approaching the intersection.

The Suburban hit the left front axle of the Camry, which came to an uncontrolled stop on the southbound grass shoulder of Route 2/4.

Parker was not wearing his seat belt and was ejected from the Camry during the collision. He was transported to Calvert Memorial Hospital, where, due to injuries sustained as a result of the collision, he was pronounced dead.

The Suburban continued across the northbound lanes of Route 2/4 and came to an uncontrolled stop in the driveway of 2010 S. Solomons Island Road.

Kreider sustained serious injuries as a result of the collision and was transported to MedStar Trauma via ground ambulance.

According to a statement from CALS by member Michael Smith, the “last update” on Kreider’s condition was that she was in stable condition.

“Additional information regarding the status of our paramedic will be released as available via our [T]witter feed,” Smith wrote in the statement. “The officers and members would like to send out thoughts and prayers to the family and friends of the paramedic and other party involved.”

A Nixle alert was sent out at 4:33 p.m. Monday stating that both the northbound and southbound lanes of Route 4 were shut down due to the accident. An alert stating that the road was open was sent out at 8:45 p.m.

Sgt. V. Bortchevsky of the Crash Reconstruction Team is investigating the events leading up to the collision. Anyone with additional information regarding the incident is asked to contact Bortchevsky at 410-535-2800, or email him at bortchvi@co.cal.md.us.
